IMPROVEMENT IN APPARATUS FOR BURNING GAS-TAR.

Specification forming part of Letters Patent No. 142,357, datedSeptember 2, 1873; application tiled April 23, 1873.

To all 'whom it may concern:

Be it known that I, ANANIAs SMITH, of Niagara Falls, in the county ofNiagara and State of New York, have invented a new and Improved Mode andApparatus for Burning Gas-Tar, of which the following is aspecification:

My invention consists in constructing the apparatusV with a reservoirfor containing the gas-tar, having steam-jackets and steam-pipes forheating it to the proper degree to increase its liquidity, and admittingsteam to the surface of the gas-tar to force it through the pipes to thecombustion-chamber.

The apparatus is fully illustrated by the drawings, of which Figure I'isa horizontal section through the iire-boX, decomposing-retort, and theburners. Fig. II is a vertical section through the reservoir.

A is a section of a nre-box. B is the decomposing-retort, of which B1 isthe pipe admitting steam thereto, and B2 the pipe through which it isconducted to the burners. C is the reservoir for the gas-tar, of which DD are steam-rin gs, connected by tubes D D. Steam is admitted to therings and tubes through a pipe, d. Steam is also admitted to the mainspace of the reservoir containing the tar through a pipe, E. c is thepipe through which the tar -is forced to the burners. This pipe is showndisconnected in the drawing. In the apparatus it is connected to thepipe c, Fig. 2. A safety-valve, F, is arranged at the top of thereservoir G to permit the escape ot' steam should an increased pressurebe created by the vaporization of a portion of the gas-tar. The pipe cmay be incased Within a larger pipe, e, through which steam is allowedto' circulate, to assist in heating the gas-tar before it passes to theburners. G G are'the burners, consisting of the small tubes c forconveying the gastar, they being passed through the crosses ff in thepipe B2. Short pipes g g, having notches or slots i'rmed in their endsaround the central bore, are passed over the ends of the pipes c andscrewed into the crosses f. H H and H Vare cocks for shutting off andregulating the supply of gas to the burners. I is a similar cock forshutting oft' and regulating the steam.

Air is admitted through the door; or suitable openings may be leftaround the burners to admit regulated quantities of air to the fire; orair may be forced into the steam-pipe in a heated state, as shown at J,Fig. 1. Suitable valves j are arranged t0 regulate the quantity of airto be admitted.

Assuming that from the above description and the drawings theconstruction of the apparatus, With its various modifications, is fullyunderstood, I shall now proceed to describe the mode of its operation.

The reservoir() being supplied with a suiiicient quantity of gas-tar,and the tar having been sufficiently heated by the steam in the tubes Dto cause it to flow readily, steam from the boiler is admitted theretothrough the pipe E, which forces the tar through the pipe c to theburners. Simultaneously with the admission of steam to the reservoirsteam is also admitted to the decomposing-retort B through the pipe B1.After passing through the retort it passes through the pipe B2 to theburners, issuing through the slots, and commingling with the gas-tar asit issues from the i smaller tubes.

A light fire of, coal or wood may be kept in the furnace; or the tar anddecomposed steam may be ignited by other means.

I claim- The combination of the reservoir C, having steam-rings D D andsteam-tubes D D', the tar-conducting pipe c, and the burner or burnersG, substantially as shown and described.

ANANIAS SMITH.
